T at whom, it may concern:

Be it known that I, WILLIAM WHITE, a subject of the Queen of GreatBritain, residing at Birmingham, county of Warwick, England, haveinvented certain new anduseful Improvements in Regenerative Gas-Lamps,(for which Ihave obtained Letters Patent in Great Britain, No. 21,775,dated November 29, 1892, and in France, No. 232,953, dated September 21,1893,) of which the following is a specification. r

This invention relates to regenerative gas lamps and more especially tothose intended to be used upon brackets or standards or [5 otherwisesupported upon bases below them in place of being suspended from above.

This invention contemplates principally an improved method of and meansfor controlling the air admitted into the regenerator, also a method ofsupplying air within the rim of the globe from above and a method ofsecurely attaching the glass or other funnel to the regenerator.

In the annexed drawings, Figure l is an 2 5 elevation of the lamp. Fig.2 is a plan View of the regenerator as seen from below; Fig- 3,avertical section of the lamp on the line 3,

3, Fig. 2, the left half being a central section.

Fig.4 is a partial plan view of the metal ring or plate surrounding theregenerator, and Fig. 5 is a side elevation of a piece or strip of suchring or plate. Fig. 6 shows a suitable tool for removing the regeneratorand chimney when lighting the lamp.

A represents the burner, at the summit of the gas feed pipe B whichpasses through the center of the cylindrical fitting O, the flange D ofwhich supports the glass globe E which rests upon the washer F on theflange. The 40 lower end of the fitting O is made to screw onto or inthe usual nozzle of a gas bracket, chandelier or the like, and above thescrew threaded portion the fitting is cylindrically hollowed out but toretain the flange C in its center or an equivalent flange to carry thewire gauze or equivalent diaphragms G. Below the diaphragms and belowthe flange D are holes H in the wall of the fitting, and above thediaphragms and above the flange D are the holes H which can be, made ifdethe glass globe.

sired by recessing the upper edge of the cylindrical wall. The spacewithin the cylin drical fitting O is closed above by the cover disk Jthrough which the gastube B passes.

The regenerator may be of any suitable kind. That illustrated is of thatform in which the air is supplied through radial pas-. sages K to acentral chamber K while the products pass upward in the intervals Kbetween the walls of the said passages, and the .incoming air is keptseparated from the products by a. downwardly directed cylindrical flangesurrounding the central air chamber which is open below. Thisregenerator with its flanges has heretofore been generally 6 made in onepiece of cast metal. For the sake of lightness, the plate L which restsupon the upper edge of the glass globe E and carries the regenerator andchimney (the weight of which parts is therefore borne by the glass) ispreferably made of stamped thin metal, such as copper, and with theinterior air deflecting flange M of similar material is secured to theflange K on the regenerator. The flange K is also formed on theregenerator to receive and center the annular channeled ring N whichisJinedwith asbestos and serves to receive the lower edge of the taperedchimney 0 preferably made of opal glass.

The plate L is made with a number of pyramidal recesses or depressionson its under side and consequently reappearing as raised pyramids on itsupper side. In the outwardly directed face of each of these recesses isa perforation for admission of air which passes by way'of the saidrecesses over the edge of the glass globe and into the lamp. Thisincoming air is deflected downward and equalized by the corrugatedflange M under the plate L which lies just within the edge of P is acylindrical flange on the upper face of the burner and P a pin on theregenerator which engages inthe socket formed by the flange and centersthe regen- 5 erator on the lamp. This pin lies in the center of theregenerator and serves to prevent the regenerator being accidentallyshifted off the globe, but the said pin does not bear the weight of theregenerator. Ioc

edges are serrated. By bend ng outor back i the serrated points more orlesseither along the whole length or at any point, the regulation of airinlet may be controlled so as to give any desired form to the flame.This strip is wrapped round to form a ring and is secured by a wire Q.

R is an outer annular perforatedeover plate of any desired ornamentalform and preferably of enameled metal.

S is the central rod rising from the regenerator and carrying the frameor spider T which holds the upper edge of the chimney and is securedthereon by the nut U screwing on the rodS as is usual in lamps of thisclass. However, according to the present invention the nut U is formedwith an eye or eyes forming two passage ways V V, the one for the chainby which the upper removable part of this lamp may be attached to thegas bracket, or otherwise for its suspension when not resting on theglass globe, the other for receivniture, &c.

metal flanges L and M secured thereto,

ing a tool such as illustrated in Fig. 6 for eifec t'ing such removal orreinstatement. This enables the regenerator to be removed even when hotand remain suspended from the gas bracket, &c., without touching anyfur- I claim as my invention- 1. The combination witha regeneratorhaving exterior air entrances, of a strip of sheet metal wound aboutsaid regenerator, the said strip having corrugations in the direction orits circumferential length and adj ustable'ser- 1 rated edgessubstantially as and for the purpose described.

2. The combination with a cast metal regenerator body having a flange Kof shaet e flange L having pyramidal perforated depressions on its underside, and the fiangeM being corrugated all substantially as hereindescribed.

In witness whereof I have signed this specio fication in presence of twowitnesses.

WILLIAM WHITE.
